Methods and apparatus for feeding sheet |
摘要 |
Apparatus for feeding flexible sheet (2) onto an inwardly facing curved surface (6) of an imagesetter comprises a feed system (3,4,7,8) for feeding the sheet from an input side onto and along the surface towards an output side. The feed system is also adapted to exert a force in the plane of the sheet (2) to cause the sheet to flex into conformity with the surface (6) and to form a ridge near one side. A monitoring system (12) monitors for formation of the ridge as an indication that the sheet conforms to the curved surface.
